Giant downdraft tower might create 500 MW of power

Solar Wind Energy hopes to construct a 2,250-foot-tall, wind-powered tower on the Arizona-Mexico border that would generate 500 megawatts of power. The project, which consists of the $1 billion tower, a plan to pipe desalinated water in from the Sea of Cortez in Mexico and a desalination plant, is expected to create 2,500 construction and transportation jobs. When water is sprayed into the hollow tower's opening, it creates very humid and heavy air, which sinks down the tower. The sinking ir can accelerate to 50 mph and then exit the tower and spin turbines.
